I recently noticed a problem with Microsofts Remote Desktop Client (mstsc): it starts a terminal session in full-screen mode, but once I resize it to work in a local application, I cannot get it back into full-screen by double-clicking on the title bar, if the local screen resolution is higher than the server’s screen resolution.
I found the solution in Jeff Atwood’s Remote Desktop Tips at Coding Horror: it’s Ctrl+Alt+Break. Visit his page to find more helpful key combinations.

Thanks, first site I came across with this simple fix, thanks for republishing it!
It’s perfect. A simple press of the keys and it’s fixed! Thank you.
Wow, here I am pressing F11, double clicking things, looking for some menu I can change the settings in, etc. It’s too simple, thanks a million for posting it!
wow,thanks for this.Struggled with this for almost the whole day
What if I don’t have a break key? Any further tip?
Thank you for publishing this tip!

excellent! thanks a ton!
Those who don’t have “break” button on your keyboard, look for the “pause” function key at the right “shift” button.
If your keyboard is like mine, just press [ctrl + fn + alt +right shift] instead.
None of the key combinations worked for me, this worked though: http://www.lunarmill.co.uk/blog/remote-desktop-windows-7-restore-full-screen-view-mode/
